GoT: Decreasing DCC Queuing for CAM Messages. IEEE Communications Letters, 24(12), 2974–2978.1089-7798https://hdl.handle.net/10016/32038Vehicular networks use Decentralized Congestion Control (DCC) mechanisms to operate effectively, but this mechanism may introduce queuing delays. Freshness of Cooperative Awareness Messages (CAMs) is critical for their usefulness. In this letter we explore how the presence of other types of traffic additional to CAMs, even with lower priorities, has an impact on the freshness of CAM messages due to DCC queuing. Finally, we propose Generate-on-Time (GoT), which is a simple mechanism that reduces DCC queuing delays for CAM messages without introducing any downside in other performance metrics.5eng© 2020 IEEE.Cooperative awarenessEnd-to-end delayEtsiIntelligent Transport Systems (Its)Vehicular networksresearch articleTelecomunicacioneshttps://doi.org/10.1109/LCOMM.2020.3019515open access2974122978IEEE Communications Letters24AR/0000026438
